independent solution for the Enterprise.
This document outlines an estimate of hardware and software requirements for
deploying Oracle Primavera P6 Enterprise Project Portfolio Management product.
Three deployment scenarios are considered – small, medium, and large – and
recommendations for each type are provided. These recommendations should only
be considered as guidance for planning product deployment.
The following assumptions are made in this document:
• A highly available environment is desired.
• Database specific best practices for high availability, backup, and recovery
are being followed.
• Load balancing specifics, software and hardware, is beyond the scope of
this document.
Many improvements and feature enhancements have been implemented in the
Primavera P6 EPPM R8.1 product. The P6 Services, Summarizer, and Leveler
modules are re-architected to be platform independent, robust, reliable, and highly
scalable. P6 R8.1 has also introduced a near real- time reporting solution called
Publication. There is a full whitepaper that describes this new feature in detail
available, it is titled P6 Extended Schema White Paper.

ARCHITECTURE OVERVIEW
Oracle Primavera P6 Enterprise Project Portfolio Management is a Java 2 Platform,
The division of tiers allows the application
Enterprise Edition (J2EE platform) web application. The J2EE platform consists
to scale according to customers’
performance demands. for a set of industry-standard services, APIs, and protocols that provide the
functionality for developing multi-tiered, web-based, enterprise applications. The
division of tiers enables the application to scale according to customers’
performance demands. Oracle Primavera P6 Enterprise Project Portfolio
Management uses the J2EE specification to build a flexible and scalable cross-
platform solution.
The main tiers of Oracle Primavera P6 Enterprise Project Portfolio Management
are:
• The presentation tier – A web server layer rendering JSPs, JavaScript,
Applets etc. to present a feature- rich UI accessible through various
supported browsers.
• The middle tier – A J2EE application server forms the middle tier where
all business logic of Oracle Primavera P6 Enterprise Project Portfolio


Management is implemented. This layer runs the business logic for both
the P6 Web application and the P6 Services.
• The data tier –The data tier consists of a standalone or clustered RDBMS
environment utilizing Java Database Connectivity (JDBC) to integrate with
the middle tier.
The Oracle Primavera P6 Enterprise Project Portfolio Management application
resides on an application server, and the repository of the application data resides
on the database server. Figure 1 illustrates the architecture of Oracle Primavera P6
suite of Products.

Typical Oracle Primavera P6 Enterprise Project Portfolio Management
deployments consist of the following components:
• A clustered web server load, balanced using a load balancing router or
software solution. End-users including administrators interact with
Primavera P6 through these Web servers.
• A clustered J2EE application server on which Oracle Primavera P6
Enterprise Project Portfolio Management is deployed.
• Oracle Primavera P6 Enterprise Project Portfolio Management uses a
RDBMS as its data repository. Depending on the dataset size, the database


server can be a standalone or a clustered server. In the following sample
architecture, the database is clustered. For optimized performance, the
application servers and RDBMS are co-located, for example, within the
same subnet.

PERFORMANCE AND SCALABILITY CONSIDERATIONS
While there are multiple ways to achieve the desired performance and scalability
levels in Oracle Primavera P6 Enterprise Project Portfolio Management, the
performance considerations can be grouped in two categories: Vertical and
Horizontal. There are several advantages (and disadvantages) for choosing one over
the other. Organizations can decide which to use, based on:
• The desired level of performance
• Availability requirements
• Short-term vs. long-term outlook of system usage
• Seasonality and frequently used application areas

Vertical Scaling (Scaling up)
Vertical scaling involves adding additional resources, or upgrading resources on an
existing system. Vertical scaling is usually a good approach if the application
bottlenecks are processor and memory-related.


JVM Heap Size

The application objects (such as Projects, Activities, and Assignments, etc.) are
stored in the Java Virtual Machine (JVM) heap allocation. Most of these objects are
short- lived, and are periodically cleaned up by the JVM’s garbage collection
mechanism. As the number of concurrent users increases, performance and
scalability is affected by the available heap space in the JVM. Increasing the heap
size is an easier way to achieve the desired performance and scalability.

Hardware Upgrade

Desired performance and scalability can also be achieved by upgrading the CPU,
adding extra cores, upgrading to faster I/O devices, and upgrading from a 32-bit to
64-bit hardware. The recommend hardware is 64-bit.

Operating System Upgrade

Another way to achieve the desired performance level is by doing such things as:
upgrading to latest versions of the operating system, installing latest patch updates,
and upgrading from 32-bit version to a 64-bit version. The recommend hardware is
64-bit.
While vertical scaling is easier to achieve, it does not address the availability
requirements. If the desired level of availability is high, then vertical scaling alone
will not be sufficient.

Horizontal Scaling (Scaling out)
As the demand for applications grows, additional nodes can be added to an existing
application server cluster to handle the increased system load. For high availability
requirements, horizontal scaling is the better option.

Adding Application Server Nodes

As the usage of applications grows within the organization, adding additional server

quarter for maintenance. Adding or removing application server nodes should be
considered to manage seasonality. To mitigate risk of degraded performance and
undesired downtime, it is crucial to understand the business cycles of the
organization and to plan for the required level of performance, availability, and
scalability.

Database Scaling and Clustering
Database server scaling options are available, and have been widely adopted and
implemented. Database clustering enables multiple nodes in a clustered system to
mount and open a single database that resides on shared disk storage. This
configuration provides high availability in the database environment. One example
of database clustering is Oracle Real Application Clusters (RAC).


DEPLOYMENT CONSIDERATIONS
Oracle Primavera P6 Enterprise Project Portfolio Management performance
depends on the load faced and response characteristics of each tier discussed in the
previous section. Performance- affecting factors are identified and discussed in the
following sections. These factors should be considered during deployment
planning.

Oracle Primavera P6 Web Client
The number of concurrent users accessing the system directly affects the web client
performance. Performance is also affected by the activities being performed within
each user session (for example, Activity Gantt, Resource Planning, Scheduling,
Leveling, Summarizing, and Reporting, etc.). Concurrent users and their system
activities largely affect CPU and memory requirements of the application server.

Oracle Primavera P6 Server
The Oracle Primavera P6 Enterprise Project Portfolio Management server is a
J2EE application that uses J2EE technologies for interaction with end-users, target
systems, database repository, etc. Following are some areas of server operation that
need to be considered during Oracle Primavera P6 Enterprise Project Portfolio
Management sizing.

P6 Services

In Primavera P6 R8.1, the service process can now run as a standalone application
For most deployment categories, we
for better performance and scalability, and is platform independent. Services are
recommend setting up a dedicated
application server node for running job
responsible for executing real-time and scheduled application jobs. The following
service. application areas are processed as jobs:
• Summarizer
• Scheduler
• Leveler
• Publications


The Services are capable of processing large number of projects, activities, and
resource assignments. The number of concurrent jobs largely affects the CPU and
memory requirements of the application server and the load on the database
servers.
• For medium to large deployments, setting up a dedicated application
server node for the services is recommended. This application server
should not be part of the cluster that processes HTTP requests from the
web client. In addition, turning off the services on the application servers
in the cluster, which are serving web client requests is recommend.
Horizontally scaling out by adding more dedicated Services application
server nodes can address increased performance requirements.
• For long- running jobs, off-peak hours job scheduling is recommended.
For example, scheduling a job to run, when the load on the system is low.
• For the initial run of the Publication Services, after install or upgrade of
P6, running off-peak hours such as over the weekend is recommended.
• For heavily data- intensive jobs (such as summarizing an entire EPS)
sequential, rather than concurrent scheduling, is recommended. For
example, do not schedule two large EPS summarization jobs to run at the
same time.

Publication

The newly designed Publication Services allows for near real time reporting of
Project data. The following factors could impact the response time and resource
for Publication:
• Number of Activities/Assignments
• Length of project
• Length of Publication date range
• Length of Activities/Assignments
• Number of Financial Periods

Activity Gantt

The Activity Gantt feature underwent scaling efforts to help large deployments.
Small deployments also benefit from this enhancement because of optimization in
code to help load data quicker. The last release had a limit that enabled the user to
load 15k activities. This release has raised the limit to 100k activities.


The following factors could impact the response of the Activity Gantt feature:
• Number of Activities/Assignments
• Number of activity Relationships
• Number of currently opened projects
• Project length
• Depth of WBS Hierarchy
• Activities/Assignments Length
• Amount of client side memory allocated to the JRE and applets
• Other load on the application server

Resource Management

The Resource Management feature now allows for a more interactive resource
manage approach. Resource management is now easily and intuitively
accomplished. The following factors could impact the response time of the
Resource Management:
• Number of Resources
• Number of Resources Assignments to Activities
• Filter usage
• Project length
• Depth of WBS Hierarchy

Risks

The Risk feature has been completely redesigned to enable a high confidence level
of success by evaluating factors such as cost and scheduling. The following factors
could impact the response of the Risk feature:
• Number of Risks
• Number of Activity Assignments to Risk
• Number of Risk Scoring Matrix assignments
• Number of Response Plan assignments


P6 Web Services

The P6 Web Services platform employs Web-based technology to handle requests
from external programs. External client programs use P6 Web Services by creating
a request and sending it to the application server using the SOAP (Simple Object
Access Protocol.) Having received the request, P6 EPPM uses the appropriate
business logic required to service the request. The client application need not
understand the semantics of this processing. Responses or requests from P6 EPPM
simply follow the same path in reverse.

P6 Web Services can be divided into four categories of services:
• Business Object Based Services (CRUD operations)
• Job Service
• Spread Service
• Import and Export Services
Many data set characteristics can impact the performance of Web Services. All
requests should make use of meaningful filters to reduce the amount of data
returned by the service. Other aspects that can affect the performance of Web
Services are:
• System usage – P6 features in use
• Environment
• Level of hardware

DEPLOYMENT CATEGORIES
Oracle Primavera P6 Enterprise Project Portfolio Management deployments can be
classified into three categories i.e. small, medium and large. Some of the factors
considered for defining these categories are outlined in the following table.


These factors influence the hardware and software specifications during Oracle
Primavera P6 Enterprise Project Portfolio Management deployment.

DEPLOYMENT ARCHITECTURES

Small Deployment – Single Node
This deployment model is suitable for a business unit or a division within an
organization. It also is useful for setting up a pilot with the intent of moving to a
medium or large size deployment. This deployment can achieve the desired
performance or scalability, but does not address the high availability requirement
due to single point of failure.

Medium Deployment – Clustered
Assuming that high availability is desired for a medium deployment, the application
server is clustered. If high availability is not a requirement, desired scalability can be
achieved vertically by adding equivalent units of memory and CPU.
The clustered nodes can exist on the same physical machine as separate node
deployments when a high-end machine is used for the application server. A load-
balancing router can be used to load balance between the nodes for optimal
performance.

FREQUENTLY ASKED QUESTIONS

How much hardware does P6 installation require? Tables that describe the
recommended hardware for each deployment size are described earlier in this
document.

How much disk space does P6 require? The P6 application requires little space.
However, you do need enough space to run the Application Server software (such
as WebLogic). You will also need enough space to keep historic log files. You
must also ensure that you have the appropriate amount of disk space on you
database server. Recommendations can be found in the tables described earlier in
this document.

Can P6 run in a cluster? Yes, P6 can run in a cluster.

Do the P6 Services affect performance? Yes. P6 Services do affect performance
for the P6 Web application. The difference in performance depends on some of
the following factors:

• Hardware size
• Data size
• Service recurring schedules
• P6 feature usage
• Data change rate

Should P6 Services be installed on the same server as Primavera P6 Web?
Oracle Primavera recommends installing the P6 Service on a dedicated box.

Will I need more space when upgrading to P6 8.1 with Publications? Yes.
The Publication feature requires additional drive space on the database. A good
estimate is to calculate your currently used disk space and double it.

How can I make P6 Service run faster? You can make the P6 Service faster by:

• Making sure the P6 Services are installed on a dedicated server.
• Separating the P6 Services to multiple servers. If performance is a
concern, it would be a good idea to install all global services on one server
and the Project Publication service on its own dedicated server.
• Increasing default thread counts, when working with Publication Service
this only affect the Project service.
• Verifying that the database has the optimum settings for efficiency:
o Enough memory
o Fast disks
o No other database instance running

Should the database be installed in a shared database environment? No.
Oracle Primavera recommends a dedicated Database Server for the P6 Suite.


What is the best way to monitor performance for P6? You can use Oracle
Enterprise Manager to monitor many aspects of the database (Oracle Database
only) as well as OS and WebLogic exposed metrics.

What is Considered Acceptable Network Latency for P6? Enterprise
environments should have low latency networks, meaning ping times should return
in less than 1ms for best P6 performance. P6 has been tested within simulated
latency environments and offers acceptable performance up to 100ms (round trip
browser to application server). Higher latency environments have been tested, but
as with all multi-tier enterprise products, higher network latency will result in slower
response of the software suite.

How much disk space will the database schema require for table spaces?
You can find the answer for this early in this document in the “Deployment
Architectures” section.
